'l'liis invention. relates to machines for casting stereotype printingplatesV from e matrix or' mat.

The principal object of the invention is s to improve the constructionof such machines in tbe particulars hereinafter more specically referredto, A other things, a more convenient and fully 'operative machine .ofincreased efficiency lo and durability.

Another object is to provide means whereby interchangeable parte willgive a Wider range of utility to the machine.

Another object is to provide more positive l5 means for automaticallylocking the mov-v able member of tbe casting box or moldto tbcstationary ymember during the casting operation.

fi. still further object is to-provide means for adjusting tbe saidlocking means,

2o but also mounting the movable members or' the melf. bon uponasliclable frame and roviding means for shifting the seme bo ily to-Wei-rl the fixed mold member after the movable nfiernber` is swung intothe casting posilion. f i

Another object of tne invention is to provide means for raising theclamping and adjusting means after tbe casting operation, so that tbemold box 4members may be seg erated, and for holding tbe same in t e kilraisecl posit-ion. until said members are again brought into position`lor 'the casting of an other plate. i

gaim I desire to materially reduce the beating of themaebine, incidentto the casting operation, whereby more Work may be accomplisberl in agiven period. of time and the li'fe o the machine prolonged, by the useof a Water jacket, beat absorbing iins or otberr suitable means appliedto the stationary member ofthe casting box.

These anal other features of the invention will be more fully'compreliended as I proeed; with my specification in describing themachine illustrated in the accompanying rlrawings.

The invention consists in the various levices, andthe arrangement andcombination of clevices herein illustrated.,y described and moreparticularly set forth in the appended claims'. .g

General description.

1 lt will be noticed by referencey to said drawings that the machinecomprises a frame A, having an upright member l., and mi) two horizontalmembers 2. To the upri bt member is secured a vertical late B, whichforms the stationary part of t e casting box. The horizontal memberssupport a. movable l frame carryii e e tiltable table C, aclaptefl to105 bold tlie mat or matrix K and to be swung into juxtaposition againsttbe aforementioneol .stationary part to torm a mold box, the latterdesignatedv as e whole by tlio letter Ii).
